Is there an appropriate time to stop being on guard for seeing an old ex when you're dating someone new? I ask because my ex-girlfriend lives about a mile from me, and we go to a lot of the same restaurants and stores. I often worry about taking my new girl out to these places because, if we were to see my ex out in public somewhere that I knew she could very well be, then I would feel like I was somehow rubbing my new girl in her face. But, then again, I go to these certain places because I enjoy going there, and to avoid them because of her seems silly. Am I worrying too much? Is there an appropriate amount of time to wait?
